User's Manual 69. Configuration Parameters Reference
Parameter Description
configure voip > sip-
definition settings >
use-aor-in-refer-to-
header
[UseAORInReferToHeader]
Defines the source for the SIP URI set in the Refer-To header of
outgoing REFER messages.
 [0] = (Default) Use SIP URI from Contact header of the initial call.
 [1] = Use SIP URI from To/From header of the initial call.
Enable User-Information
Usage
configure voip > sip-
definition settings > user-inf-
usage
[EnableUserInfoUsage]
Enables the usage of the User Information, which is loaded to the
device in the User Information Auxiliary file. For more information on
User Information, see ''User Information File'' on page 807.
 [0] Disable (default)
 [1] Enable
Note: For the parameter to take effect, a device reset is required.
configure voip > sip-
definition settings >
handle-reason-header
[HandleReasonHeader]
Determines whether the device uses the value of the incoming SIP
Reason header for Release Reason mapping.
 [0] = Disregard Reason header in incoming SIP messages.
 [1] = (Default) Use the Reason header value for Release Reason
mapping.
[EnableSilenceSuppInSDP] Determines the device's behavior upon receipt of SIP Re-INVITE
messages that include the SDP's 'silencesupp:off' attribute.
 [0] = (Default) Disregard the 'silecesupp' attribute.
 [1] = Handle incoming Re-INVITE messages that include the
'silencesupp:off' attribute in the SDP as a request to switch to the
Voice-Band-Data (VBD) mode. In addition, the device includes the
attribute 'a=silencesupp:off' in its SDP offer.
Note: The parameter is applicable only if the G.711 coder is used.
configure voip > sip-
definition settings >
rport-support
[EnableRport]
Enables the usage of the 'rport' parameter in the Via header.
 [0] = Disabled (default)
 [1] = Enabled
The device adds an 'rport' parameter to the Via header of each
outgoing SIP message. The first Proxy that receives this message sets
the 'rport' value of the response to the actual port from where the
request was received. This method is used, for example, to enable the
device to identify its port mapping outside a NAT.
If the Via header doesn't include the 'rport' parameter, the destination
port of the response is obtained from the host part of the Via header.
If the Via header includes the 'rport' parameter without
a port value, the
destination port of the response is the source port of the incoming
request.
If the Via header includes 'rport' with a port value (e.g., rport=1001),
the destination port of the response is the port indicated in the 'rport'
parmeter.
Enable X-Channel Header
configure voip > sip-
definition settings > x-
channel-header
[XChannelHeader]
Enables the device to add the SIP X-Channel header to outgoing SIP
messages. The header provides information on the physical Trunk/B-
channel on which the call is received or sent.
 [0] Disable = (Default) X-Channel header is not used.
 [1] Enable = X-Channel header is generated by the device and sent
in SIP INVITE requests and 180, 183, and 200 OK responses. The
header includes the Trunk number, Bchannel and the device's IP
address, using the following syntax:
x-channel: ds/ds1-<Trunk number>/<B-
